SEA FOB. HOOP-IRON ENDS.

Application llecl Iuly 22, 1922. Serial No. 576,862.

To all whom. z't ma concern.'

Be it known that JOSEF BAYER, a citizen of the German Republic, and residing at Barmen-U., Germany', have invented certain new and useful lmprovements in a Seal for Hoop-Iron Ends for which l have filed an application in (germany April 1, 1921, and of which the following is a specification.

It is known to join the superposed ends of hoop-iron laid around chests, parcels,

bundles, or the like, without perforating and without riveting the same, simply by cutting orpunching tongues out of said ends and turning the same over. Thereby,

' the hoop-iron is, however, weakened in the same way as when perforating and riveting the same, which, owing to the high tensile strain to `which the4 hoop-iron is exposed, reduces the tensile strength of the latter. Furthermore, means have become known, by which a hook-shaped punchingtooth provides incisions in the hoop-iron for producing said tongues therein, or which by a double-acting punching-blade cut the tongues out of said hoop-iron ends, so that rivets or the like are not required.

Besides, it has been proposed to enclose the superposed hoop-iron ends to be joined b means of a joining member and to severally press or squeeze the joint by a pressure that is exerted at right angles, or parallel, to the plane of the joint in such a way that on top of the joint a plurality of bulbs are produced, which has the disadvantage that the latter form impediments thereon, while the production of said squeezed joint requiresv great expenditure of power. A further drawback of said, joint consists in the fact that the same can be varied by multiplying or modifying the lateral squeezings only.

The present invention provides an improved method, by means of which said hoop-iron joint and seal is produced with' the aid of such a joining member enclosing the superposed hoop-iron ends, said method consisting in providing said joint at its edges at a time with one or a plurality of fingerlike impressions, of variable design, projecting at an angle from the underside of the joint, and that by a pressure acting at right angles to the plane of the joint, while means are provided for further varying said joint and seal and making the same particularly `useful for the actual owner, by whom it is employed, as well as for his customers. By .the ngerlike impressions projectin at an angle from the underside of the joint, the upper side of the latter is left perfectly smooth and thus forms no impediment whatsoever, while the downwardly projecting ingerlike edge impressions press themselves into the material of the chest or the like around which the hoop-iron is placed.

The accompanying drawings show how the invention can be put into practice:

Fig. 1 is a sectional side view of a pres-` sure-contrivance for producing the edge impressions in the hoop-iron joint, the latter belng shown in its proper position therein.

Figs. 2 and 3 are plan views of the latter, respectively with the upper and lower part of the same in section;

Fig. 4 is a plan view of the joining member mentioned' Fig. 5 is a plan view of the finished joint and seal with one ngerlike edge impression,

Figs. 6 and 7 are respectively an edge view and a side view of the latter.

F ig. 8 is a sectional side view of a doubleacting pressure-contrivance combined with a hoop-iron stretcher, i

Figs. 9 and 10 are plan views of the latter, respectively with the upper and lower part of the same in section,

Fig. 11 is a sectional front view of the jcgarsing of the pressure-contrivance shown in F ig. 12 is an underside plan view of the punch fitting in said casing, with the pres sure-fingers thereon in section;

Fig. 13 is again a plan view of the joinin member mentioned;

ig. 14 is a plan view of the finished joint and seal with two fingerlike edge impressions produced by the double-acting pressure-contrivance,

Figs. 15 and 16 are respectively an edge view anda side view ofsaid finished joint.

Figs. 17 and 18 are plan views showing two modications of the finished joint.

Fig. 19 is a sectional elevation of a punch by means of which a further modified joint and seal shown in Fig. 20 can be produced.

Figs. 21, 22 and 23 show further moditications of a joint and seal produced according to the present invention.

he pressure-contrivance shown in Figs. 1 and 8 comprises a vertically up and down movable punch d with pressure-ngers d1 at its lower end facing a correspondingly titi lill@ LIX shaped fixed matrix a with a support 7), the hoop-iron to be joined being, with the joining member g on its superposed ends f, f1, placed edgeways between said support l; and said punch al and, by lowering the latter', provided with one fingerlike impression (Fig. 5) or with several such impressions at a time (Fig. 14) to be uniformly distributed over said joining member g, said impressions projecting then somewhat laterally from the plane of the joining member.

As shown in Fig. 17, the edge impressions may also be provided at the ends g2 otl the joiningmeniber g1 only, which engage thus the hoop-iron in hooklike fashion; or, as shown in Fig. 18, the edge impressions may be uniformly distributed over the joinin'g member g1, such as in Fig. 14, and besides provided at the ends g2 of the same, such as in Fig. 17.

As further shown in Figs. 17 and 18, the joining member g1 may on its upper surface be provided with any particular designation, for instance the trade-mark of a firm or the like', such as indicated by the words Herko or .Toba.

It will be seen that beside the great reliability of the hoop-iron joint and seal its variability is unlimited: either by providing any number of edge impressions therein, or by varying the design of said impressions, sol that, in connection with the partic'ular designations on the upper surface of the joining member, the danger of a fraudulent removal of the joint and thus of theft is reduced to a minimum.

Figs. 19 to 24 inclusive illustrate constructional froms of further variations or modifications of the joint and seal, whereby, besides, a particular strengthening of the latter is obtained.

In Fig. 20, the joint consists, as in Fig. 14, of a joining member 3 enclosing the superposed hoop-iron ends 1, 2 and having the'edge impressions 4 therein, while it is further provided with a U-shaped bend 5, which is produced therein by means of a punch 8, 9. 10 such as indicated in Fig. 19.

The middle part of the joining member 3 may also be somewhat compressed from both its edges between the two edge impressions 4, either in elongated fashion as shown in Fig. 21, or in circular fashion as shown in Fig. 22, 6 and 6a indicating the two punch members used for this purpose in the pressure-contrivance.

Instead of fingerlike edge impressions, als such of elongated formation extending up to the ends of the joining member may be provided by means of corresponding punch members indicated at 7 in Fig. 23, whereby a crosslike joint of 'extreme strength is produced.

The multiple variations of the joint and seal have the advantage that each owner remesa of the particular joint and seal, as Well as lus customers, can at once' percelve a fraudulent manipulation on the original joint and seal.
